WHEEL-SECURING DEVICE.

SPECIFICATION forming part of Letters Patent No. 380,748,dated November17, 1885.

Application filed February 20, 1885. Serial No. 156,537. (No model.)

To all whom it may concern.-

Be it known that I, GEORGE P. STEINBAOH, of Baltimore city, Maryland,have invented certain new and useful Improvements in Wheel-SecuringDevices, of which the following is a specification, reference being hadto the accompanying drawings, forming part hereof, in which- Figurel isa longitudinal section through a hub and part of a wheel, the part ofthe axle shown being in full side elevation. Fig. 2 is a view in sectionof part of an axle with my improved linchpin in its position parallel tothe axle. Fig. 3 is a similar view of the same parts, the pin being inits vertical position. Fig. 4 is a section showing a cap without thehinged lid, and Fig. 5 is a front elevation thereof.

Like letters refer to thesame parts in all the figures.

My invention relates to devices for securing wheels to axles, applicableto all classes of wheels and axles, but designed especially to beapplied to carriages, and particularly to childrens carriages, theobject being to simplify and cheapen such devices and to render themeasy of operation and not liable to misplacement by accident or bymeddling therewith, especially by children.

To these ends my invention consists in the construction, arrangement,and combination of devices, which will be now-fully described, andafterward specifically pointed out in the claims.

Referring to the drawings by letter, A is the hub, B the spokes, and (3the axle, of any ordinar; wheel. The hub A has a band, a, and cap a andis provided with a bushing, a, as is usual. The axle has aspindle, c,which has its bearing in said bushing. The axleis prevented fromentering thehub by means of the usual upset flange, c. The outer end ofthe spindle is slotted vertically at D, said slot havinglits inner end,(1, cut on a slant or bevel, the upper end of said bevel being nearestthe outer end of the spindle.

E is a linchpin having one end beveled ofl parallel, when the linchpinis parallel with the spindle,with the inclined inner wall, 11, of theslot D. This linchpin is provided with a longitudinal slot, e, reachingfrom slightly beveled end. When the linchpin is ready for use, it ispivoted in the slot in the spindle by means of a pin, 6', which passesthrough the slot 6 in the pin, and is held normally in that end of. theslot 0 which is near the center of the pin by a spring, F. The cap maybe provided with a hinged lid, G, and has an inwardly-curved plate, H,provided on the side above the hub with a notch, h.

The operation of my devices may be de scribed as follows, viz: The partsbeing in the position shown in Figs. 1 and 4, and it being desired toremove the wheel from the axle, it is only necessary to press thelinchpin upward against the-action of the spring F until the uppercorner of the beveled end shall have reached the inner edge of one sideof the bushing. The linchpin may now be turned until it reaches the aposition shown in Fig. 2, parallel to the spindle, when the wheel may beslipped off. The beveled end of the linchpin is in contact with theinclined wall of the spindle-slot, and the linchpin is thereby preventedfrom moving any further than to its par allel position, as shown in Fig.2.

In Fig. 1 I have omitted to show the curved plate shown in Figs. 4 and5. The use of the slot in said curved plate will now be described- Whenthe linchpin is in a position at right angles to the spindle, (see Fig.4,) it can only be moved upward when it exactly coincides with the notchh in said curved plate. Thus it is impossible to remove the wheel,except when it is in that one position-via, with the slot h in a directvertical line above the 1inchpin. Consequently the liability toaccidental displacement is reduced to a minimum. The spring F is alwayspressing the linchpin down ward, thus keeping it normally in the safeposition, and preventing it jumping up and striking in the slot h whenthe vehicle is passing over rough surfaces.

The cap may be entirely closed up by the hinged lid, and will at thesame time be-readily accessible.

Having thus fully described my invention, what I claim, and desire tosecure by Letters Patent, is-

bearing against its pivot, for the purpose set forth. I

3. The huh-cap having plate H, provided with slot h, in combination withslotted axle and slotted linohpin pivoted thereto, as and for thepurpose set forth.

In testimony that I claim the foregoing I 20 have hereunto set my handin presence of two witnesses.
